【摘要】：由于資源短缺、環(huán)境的污染、油價(jià)上漲以及人們對核能應(yīng)用污染的恐懼，當(dāng)今社會對清潔，可持續(xù)的能源的需求十分強(qiáng)烈，因此造就了當(dāng)下風(fēng)能發(fā)電技術(shù)和產(chǎn)業(yè)的快速發(fā)展。風(fēng)電回轉(zhuǎn)軸承是風(fēng)電設(shè)備的重要部件之一，是回轉(zhuǎn)軸承的一種。風(fēng)電回轉(zhuǎn)軸承主要用于偏航和變槳，一般有內(nèi)圈、外圈、保持架和滾子組成，內(nèi)圈或外圈帶有傳動齒，可以和驅(qū)動小齒輪嚙合傳動扭矩。由于安裝位置不易拆裝，而且拆裝的費(fèi)用比較高，拆裝需要的周期比較長，所以對風(fēng)電回轉(zhuǎn)軸承可靠性提出了十分嚴(yán)格的要求，一般情況下要求風(fēng)電轉(zhuǎn)盤軸承的壽命和機(jī)組壽命相同，并且必須能達(dá)到20年以上的水平。所以對風(fēng)電回轉(zhuǎn)軸承的研究，尤其是加工工藝對可靠性的研究十分重要 由于風(fēng)電回轉(zhuǎn)軸承是一種大型軸承，對其外圈或者內(nèi)圈輪齒的研究時(shí)，，實(shí)際試驗(yàn)的難度很大，同時(shí)需要大量的資金。所以文中以風(fēng)電回轉(zhuǎn)軸承的外圈輪齒作為研究對象，使用有限元分析軟件，對輪齒進(jìn)行了接觸、熱和熱應(yīng)力的模擬分析，獲得了各個(gè)過程中的應(yīng)力、應(yīng)變和溫度場的變化。這種方法有效的解決了實(shí)際試驗(yàn)的缺點(diǎn)。 論文完成的工作主要有：1.主要對輪齒工作過程中接觸力學(xué)進(jìn)行分析。首先建立輪齒接觸過程中的參數(shù)化模型，對齒輪的接觸過程進(jìn)行計(jì)算機(jī)仿真，然后分析接觸過程的計(jì)算機(jī)仿真結(jié)果。通過這些分析可以獲得輪齒在接觸過程中力的分布情況，可以分析出在實(shí)際的接觸中力主要分布在齒面的接觸處和齒根部分。最后對比不同輪齒的金相特征，金相特征分析可以獲得軟硬面輪齒的組織結(jié)構(gòu)，再綜合接觸仿真分析力的集中情況，判定軟硬面輪齒的優(yōu)劣。2.對輪齒在加工程中淬火的模擬分析，綜合了正交實(shí)驗(yàn)法和有限元分析法。首先確定正交實(shí)驗(yàn)的因素和水平，再根據(jù)正交實(shí)驗(yàn)的因素和水平選擇正交實(shí)驗(yàn)表。然后依照正交實(shí)驗(yàn)表獲得的各因素和水平的組合界定有限元分析的邊界條件，對輪齒進(jìn)行溫度場和熱應(yīng)力的仿真。最后用正交實(shí)驗(yàn)的結(jié)果分析方法對仿真的結(jié)果進(jìn)行分析，從而根據(jù)分析結(jié)果判斷各參數(shù)對淬火的影響。該過程是采用正交實(shí)驗(yàn)法，通過有限元分析獲得不同參數(shù)的溫度場和熱應(yīng)力分析結(jié)果，再使用正交實(shí)驗(yàn)的極差分析法進(jìn)行結(jié)果處理，最后根據(jù)分析結(jié)果推薦淬火參數(shù)。
[Abstract]:Due to the shortage of resources, environmental pollution, rising oil prices and fears of nuclear power application of pollution, in today's society of clean, sustainable energy demand is very strong, thus creating a rapid development of the wind power generation technology and industry. Wind power bearings is one of the most important parts of wind power equipment, is a rotary bearing. Wind power bearings mainly used for yaw and pitch, generally have the inner ring, outer ring, retainer and a roller. The inner or outer ring with a transmission gear, and can drive pinion transmission torque. The installation position is not easy to disassemble and assemble, the cost is relatively high, and requires relatively long cycle, so put forward very strict requirements of wind power bearings reliability, general requirements of life and the life of wind turbine slewing bearing the same, and must be able to reach more than 20 years. So the level of the wind The research of electric rotary bearing, especially the processing technology, is very important for the study of reliability.
Because of wind power bearings is a large bearing on its outer or inner gear, the actual test is very difficult, and needs a lot of money. So the outer ring gear tooth wind power bearings as the research object, using finite element analysis software of gear contact analysis and thermal simulation stress, stress in the process of obtaining, strain and temperature. This method can effectively solve the shortcomings of the test.
The main works are: 1. through the analysis of the main contact mechanics in gear working process. Firstly, the parametric model of tooth contact during the contact process of gear by computer simulation, and then analyze the simulation results of the contact process. The distribution can be obtained through the analysis of gear in the process of contact force, can the analysis in the actual contact force distribution in the tooth surface and the tooth root part. Metallographic characteristic of different gear comparison, metallographic structure analysis can obtain the characteristics of soft and hard tooth, then contact concentration simulation analysis of force, determine the simulation analysis of the gear in the process of quenching the merits of soft hard.2. the tooth, comprehensive orthogonal experimental method and finite element analysis. First determine the factors and levels of orthogonal experiment, according to the orthogonal experiment and water Flat selection table of orthogonal experiment. Then according to the orthogonal experiment table defines the boundary conditions the combination of the factors and levels of finite element analysis and Simulation of temperature field and thermal stress of the tooth. Finally, the results of orthogonal experiment analysis method to analyze the results of the simulation, according to determine the effect of various parameters on the quenching analysis results. The process is using the orthogonal experiment method, the analysis results of temperature field and thermal stress of different parameters are obtained by finite element analysis, and then use the range analysis of orthogonal experiment results, according to the analysis results to recommend quenching parameters.
